Application .filed. October 19,1912, Serial No. 726,714. Renewed May 15,1917. Serial No. 168,870.

To all whom it may concern:

13 it known that I, IVILLIAM J. KENNEDY, a citizen of the United States,residing at Jersey City, in the county of Hudson "and State of NewJersey, have invented a new and useful Drill-Stand,of which thefollowing is a specification.

This invention relates to stands for holding hand, orelectrically-operated drills, and the like, in operative position; andthe object of my invention is to provide a stand. of the characterdescr1bed which may be quickly adjusted to hold a drill in any positiondesired and in av firm manner; a further object of my invention is toprovide a stand of the character described which will be cheap tomanufacture and eflicient in use.

The invention is illustrated in the accompanying drawing, in which-Figure 1, is an elevation of a drill stand constructed according to myinvention, in operative position, a part being broken away to show theconstruction; and

Fig. 2, is a plan view of the supporting arm in position.

In the drawing like numerals of reference refer to the same parts ineach of the views.

In practice I provide a drill stand comprising a tubular part 8, on thelower end of which is fixed a collar, or base 4, whereby the tubularpart is supported in an upright position. I also provide ascrew-threaded shaft 5, preferably carrying a head 6, which may bepivotally connected with the shaft 5,

as shown at 7, so that the head will readily adjust itself to anyobject, as 8, against which it may be placed, as will be readilyunderstood. Mounted on the shaft 5, is a nut 9, and I also prefer to usea washer 10, sufficient in size to be interposed between the nut 9, andthe open end 11, of the tubular part 3 whereby the shaft 5, may be movedlongitudinally of the part 3 by the rotation of the nut 9, withoutfrictional contact between the nut 9, and end 11, of the tube.

On the tubular part 3, I mount an arm 12, having a clam ring part 13,which may be operated by a olt 14, and nut 15, whereby the arm 12, maybe secured at any longltudinal point of the tube 3, and in any ra dialdirection. The arm 12, is preferably providedwjth a plurality ofrecesses 16,

vadapted to engagea drilling device, as 17,

and hold the same against slipping when being used, as willbeunderstood.

.portand the object, preferably with the base 4, against the support;the shaft 5, is then drawn out until the'head 6, 1s against the object;the nut 9, is then screwed down the shaft 5, until the washer 10, hasbeen brought into close contact with the end 11, of the tube, and isthen turned a sufiicient distance additionally to cause some stresswhereby the stand will be rigidly held in position, a will beunderstood. The arm 12, is then adjusted longitudinally of the tube 3,and positioned to hold the ratchet, or other drilling device in theright position for drilling the desired hole, either with the drill inthe position as indicated in dotted lines in Fig, 1, or on the otherside of the arm drilling through the object against which the base 4,rests, for it is evident that th arm 12, will support a drilling devicein exactly the same manner whether located above the arm, or below thearm so that in general it will make no difference whether the head 6, isplaced against the object to be drilled, or the base i, is placedagainst it.

In the drawing I have indicated that my drill stand is to be used withan ordinary hand ratchet drill. I do not wish, however, to limit myinvention to such a use for the reason that it is equally suitable foruse with an electrically-operated, or air-operated drill.

It is common practice now in drilling a hole within the fire box of aboiler, or in other confined spaces. to block the drilling device up inplace with a number of block at great trouble and with considerable eX-pense. lVith my stand a drill can be quickly placed in position and heldthere without a large amount of material in the way to interfere withthe workman. Then, too, as the arm 12, can be turned in any radialdirection, it is evident that the stand, or rather the upright partthereof can be placed within a confined space, as a fire box, at a pointto interfere in the least possible manner with the workman and yet havethe drill held in the right position for drilling the desired hole. i

Having thus described my invention,what I claim as new and desire tosecure by Let ters Patent of the United States, is

1. A drill stand comprising a tubular part having a base, ascrew-threaded shaft adapted to slide therein, a nut mounted on saidscrew-threaded shaft and adapted to bear against one end of said tubularpart whereby said shaft and tubular part may be moved longitudinallyrelative to each other, and an arm adjustably mounted on said tubularpart, for the purpose set forth.

2. A drill stand comprising a tubular part having a base, ascrew-threaded shaft adapted to slide therein, a nut adapted to forcesaid shaft out of said tubular part, and a radiallyextending armslidably mounted on said tubular part and means to clamp said arm in anyposition, for the purpose set forth.

3. The hereindescribed drill stand comprising a cylindrical tube havinga'collar or base on one end, a shaft adapted to slide therein said shaftbeing screw threaded, a head pivotally mounted on the end of said shaft,a nut and washer adapted to engage the open end of said tubular part andforce said shaft in an outward direction, and an arm having a dividedend adapted to encircle said tubular part and having a bolt mountedtherein whereby clamping engagement may be made with said tubular part,said arm having a plurality of recesses adapted to engage a drillingdevice, for the purpose setforth.
